Description

[Detailed Description of the Invention] The present invention relates to a lighting duct mounting device, and more specifically, a locking piece 3 is suspended downward from the tip of the upper horizontal piece 2 of a U-shaped metal fitting 1, and a U-shaped A plate material 7 having a hook portion 6 at the tip is inserted into the hole 5 in the approximate center of the vertical piece 4 of the metal fitting 1, and a female screw hole 9 is provided in the lower horizontal piece 8 of the U-shaped metal fitting 1 to form a C that will become the ceiling structural material. Attach a field edge 11 to the bottom surface of the channel 10 at right angles to the C channel 10, hook the ]-shaped metal fitting 1 to the C channel 10, and lock the locking piece 3 to the edge of the upper piece 12 of the C channel 10. Then, the hook part 6 at the tip of the plate material 7 is locked to the edge of the lower piece 13 of the C channel 10, and the plate material 7 is
The deformable parts on both sides of the elongated hole 14 of the plate material 7 provided between the rear end and the vertical piece 4 are bulged outward, and the bulged part 16 is pressed against the vertical piece 4 to form a U-shaped metal fitting. 1, the lower horizontal piece 8 and the lower surface of the field edge 14 are set at almost the same height, and the screw 18 inserted into the lighting duct 17 is screwed into the female screw hole 9 of the lower horizontal piece 8. It is.

Lighting duct 1, commonly referred to as wiring duct
7, when installing the lighting duct 17 parallel to the C channel 10 (that is, at right angles to the field edge 11), which is the ceiling structural material, tap the lighting duct 17 directly to the field edge 11 from below. Since the lighting duct 17 only needs to be attached with the screws 19, it is sufficient to attach the lighting duct 17 to the ceiling material 20 as long as there is an embedding groove 21 for embedding the lighting duct 17 therein.

However, when installing the lighting duct 17 at right angles to the C channel 10 (that is, parallel to the field edge 11), it was impossible to install it because the field edge 11 for fixing the lighting duct 17 did not pass through.

Therefore, there is a method in which a field edge 11 for installing the lighting duct 17 is specially installed in advance at the planned installation location of the lighting duct 17 as shown by the imaginary line in Figure 1, and then a groove 21 for installing and embedding the ceiling material 20 is cut. , a separate roof edge 11 is required, and a lighting duct 17 is installed at an arbitrary position after the ceiling construction is completed.
There was a problem in that it could not be installed if one wanted to.

The present invention was devised in view of the above points, and its purpose is to attach a U-shaped metal fitting to a C channel, and to make the lower horizontal piece of the U-shaped metal fitting and the lower surface of the edge almost at the same height. By making the hook part C The deformable portions on both sides of the elongated hole of the plate, which is engaged with the edge of the lower piece of the channel and is provided between the rear end of the plate and the vertical piece, are bulged outward, and the bulged portion is turned into a vertical piece. By pressure welding, it can be easily fixed by inserting a jig such as a screwdriver into the long hole and bulging the deformable part outward, and it is easy to attach the ]-shaped metal fitting to the C channel. The purpose of the lighting duct installation is to provide a lighting duct installation device that can perform the work quickly and reliably.

The present invention will be explained in detail below using examples.

1 in the figure is a U-shaped metal fitting, in which a locking piece 3 hangs downward from the tip of the upper horizontal piece 2, and a vertical piece 4 of the U-shaped metal fitting 1.
A horizontally elongated hole 5 is provided approximately in the center of the metal fitting 1, and a female threaded hole 9 is provided in the lower horizontal piece 8 of the bracket 1.

A plate member 7 is inserted into the hole 5, and a hook portion 6 is provided at the tip of the plate member 7, and a removal stop portion 22 is provided at the rear end.

An elongated hole 14 parallel to the longitudinal direction of the plate material 7 is provided at the rear of the plate material 7, and the elongated hole 14 has a size such that the tip of a jig such as a driver can be inserted thereinto.

By providing the elongated hole 14 in this manner, both sides of the elongated hole 14 become narrow deformable portions.

A plurality of C channels 10, which serve as ceiling structural members, are arranged in parallel to each other at regular intervals in the attic space.

This C channel 10 is suspended from a slab or the like using a hanging device.

On the lower surface of the C channel 10, a plurality of field edges 11 are attached at regular intervals at right angles to the C channel 10.

Here, the vertical length of the vertical piece 4 of the character-shaped metal fitting 1 is equal to the distance from the upper surface of the C channel 10 to the lower surface of the field edge 11.

In the figure, 17 is a lighting duct generally called a wiring duct.

23 in the figure is a conductive wire provided in the lighting duct 17.

Moreover, a ceiling material 20 is attached to the edge 11.

In the illustrated embodiment, the ceiling material 20 is shown as a two-layer example consisting of a plaster board 20a and a ceiling material 20b, but the ceiling material 20 may not be provided with the plaster board 20a.

When installing the lighting duct 17, a groove 21 for embedding is cut into the ceiling material 20, and the bracket 1 is inserted into the groove 21 to form a U-shape as shown in Fig. 4a. Hang the metal fitting 1 diagonally on the C channel 10, then hold the locking piece 3 on the edge of the upper piece 12 of the C channel 10 with the character-shaped metal fitting 1 in a vertical position, and slide the plate 7. The hook portion 6 at the tip is locked to the lower piece 13 of the C channel 10.

In this state, a jig 24 such as a screwdriver is inserted into the elongated hole 14 and the jig 24 is rotated as shown in FIG.

Then, as shown in FIGS. 5A to 5S, the deformable portions on both sides of the elongated hole 14 are bulged outward to form a bulge 16.

In this case, the bulging portion 16 comes into pressure contact with the vertical piece 4, and the U-shaped metal fitting 1 is fixed to the C channel 10.

In this case, the lower horizontal piece 8 of the character-shaped metal fitting 1 and the lower surface of the edge 11 are approximately at the same height.

Next, the writing duct 17 is fitted into the groove 21 for embedding, and the screw 18 that is applied to the lower horizontal piece 8 of the letter-shaped metal fitting 1 and inserted through the lighting duct 17 is screwed into the female screw hole 9 of the lower horizontal piece 8. It is.

Thus, in the present invention, the ]-shaped metal fitting is hooked to the C channel, and the locking piece is locked to the edge of the upper piece of the C channel,
The hook part at the tip of the plate is locked to the edge of the lower piece of the C channel, and the deformable parts on both sides of the long hole of the plate provided between the rear end of the plate and the vertical piece are bulged outward. The bulge is pressed against the vertical piece, and the lower horizontal piece of the U-shaped metal fitting is flush with the lower surface of the field edge, so even if it is perpendicular to the C channel (that is, parallel to the field edge). The lighting duct can be easily installed, and the lighting duct can be easily installed in any position even after the ceiling has been installed.Also, when installing the U-shaped bracket, it is necessary to attach the locking piece. Lock the hook part at the tip of the upper piece of the C channel to the edge of the lower piece of the C channel, and at the same time lock the hook part at the tip of the waist plate material to the end edge of the lower piece of the C channel. Since the deformable parts on both sides are bulged outward and the bulged parts are pressed against the vertical piece, both sides of the long hole can be deformed by inserting a jig such as a screwdriver into the long hole and rotating it. The part can be easily bulged outward] The shape fitting can be easily attached, and the lighting duct can also be attached easily.
